Click on Items to Include Button is the on the Far Left of the Button Bar in the Right Panel.
You will see a left panel where you can pick and choose facts to include or include all facts. And, you can pick and choose which facts show alternative names or don't show alternative names.
Click on the "+" sign to the upper right of that panel. You can pick some, or pick all.
This is not very intuitive. As examples:
Show only Preferred Facts - (ie Don't include Alternative Facts)
Select Residence (or similar fact with alternatives) in the left panel - you will see the Options Box at the bottom of the left panel. Check the box for including only the preferred fact.
To include Alternative Residences:
Select Residence in the list of facts. Then, click on the Options box at the bottom of that panel. Uncheck the box for including Preferred Name Only.
Now, turn on the Global Command in the right hand area where you select notes and sources, etc: "Include Only Preferred Facts". That will include alternatives for all facts where you have selected to include alternative. It will NOT include alternatives for facts where you have chosen NOT to include alternatives.
Note the Name Fact & Other Vital facts are a bit different. If you select "Only Preferred Facts" - you will get only the preferred Name. If you uncheck "only preferred facts" you will get all of the alternatives. In other words, you can't pick and choose whether to choose all names if the Preferred Names is picked.)
Hope the above is not too confusing. Try playing with it and you will see how it works.
